This invention appertains to improvements in radiators for heating'systems particularly adapted for use on automobiles. The present invention aims to provide novel heating means for automobiles, wherein the hot water of the engine circulatory cooling system is passed through radiator structures also of novel construction to heat the interior of the vehicle.

The prime object of the invention is to provide novel radiator units for interposition within a circuitous connection from the engine cooling'system, and wherein the radiator structures are of such compact construction as to permit their disposition within a limited space.

Another important object of the invention is to provide radiator units constructed in such a manner as to provide the passage of an air stream through the hot water pipe thereof, so as to increase the heat radiating surface of the radiator.

'These and other objects of the invention will become more apparent to the reader after the invention is considered from th following description and claim.

. In the drawings:

Figure 1 represents a fragmentary and partial sectional view of an automobile equipped with the heating system.

Figure 2 represents a dlagrammatic view of the heating system.

Figure 3 represents a longitudinal sectional view through one of the radiator structures.

Figure 4 is an end elevation of the radiator structure shown in Figure 3.

Figure 5 is a cross sectional view of the radiator structure shown in Figure 3.

Figure 6 is a fragmentary partial sectional View disclosing one of the air plugs used on the radiator.

Figure 7 is-a fragmentary top plan view of a radiator showing the air valve.

Referring to the drawings wherein like numerals designate like parts, particular attention is first to be given to the diagrammatic view of Figure 2. This view discloses fragmentarily a conventional engine A of the internal combustion type.

Associated with the engine, in the usual manner is the water cooling radiator B. The connection C serves to return water from the water jacket of the engine A to the radiator B, while the pipe connection D permits water to flow from the radiator after having been cooled to the engine A through the usual pump E. In carrying out the present invention, a T-fitting 1 is interposed in the respective pipes C and D.

Now referring to Figure 3, the type of radiator employed in certain typesof auto-' water is to circulate. The partitions 3 serve to obstruct the flow of water at certain ends of the pipes 4 so that the water will circulate through the radiator in a zig-zag manner.

Through each of the water tubes 4 and an air tube 5 is disposed. Each air tube extends completely through the water tube longitudinally and opens at its res ective ends through the outermost sides of the header structures 2-2.

The header structures 2-2 are formed with openings 6 at one end and at opposite ends with respect to each other. One of these openings serves as the inlet for the hot water whereas the other serves as the outlet.

The foregoing description characterizes the invention as a means for heating automobiles in a quick and eflicient manner and is descriptive of a structure possessing no intricate parts and being obviously capable of being cheaply manufactured.

It is of course to be understood that certain changes, particularly in materials, shape and size, in the production of this device may be resorted to, without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

A radiator of the character described structures, a plurality disposed between the prising a, pair of header of hot water pipes header structures and secured thereto, the said pipes communicating with each other within said header structures to provide a. continuous hot water conduit, and an air tube extending through each water pipe and being opened at its ends through the said headers.
